Composition comprising at least one polymer containing hetero-atoms and at least one inert filler and methods for use

ABSTRACT

A physiologically acceptable composition containing at least one liquid fatty phase which comprises at least one structuring polymer having a polymer skeleton which comprises at least one hydrocarbon-based repeating unit comprising at least one hetero atom; and at least one inert filler. Said polymer is in particular a polyamide. This composition is more specifically an anhydrous lip composition or an anhydrous foundation.

[0001] The present invention relates to a care and/or treatment and/ormake-up composition for the skin, including the scalp, and/or for thelips of human beings, and/or for other keratin materials, such askeratinous fibers, containing a liquid fatty phase, structured with aspecific polymer containing a hetero atom. This composition is stableover time and is especially in the form of a make-up stick and moreespecially a foundation stick or a stick of lipstick, whose applicationproduces a migration-resistant deposit which shows good staying power orlong-wearing properties.

[0002] The foundations currently marketed are usually either in the formof a liquid packaged in a bottle, or in the form of a product compacted.in a case (see, for example, U.S. Pat. No. 5,186,318). Thesefoundations may require the use of an applicator such as a sponge, whichmay rapidly become contaminated and must be cleaned very regularly,especially after each application. Thus, users of foundations areincreasingly on the lookout for solid foundations in stick form, inorder to dispense with the sponge-type applicator. Such a foundation maybe easy to use, hygienic and can be applied until all of the product hasbeen used up, unlike a conventional foundation applied with a sponge.Furthermore, the surface of the foundation may remain smooth, whereasthe surface of a product compacted in a case may become deformed underthe pressure of the successive uptakes onto the applicator. Finally, afoundation in stick form may allow a uniform make-up effect to beobtained.

[0003] Conventional lipsticks and concealer products are also usually inthe form of a stick, as are deodorants and lipcare or antisun lipproducts.

[0004] These cosmetic or dermatological products contain a structuredliquid fatty phase, i.e., a phase which is gelled and/or rigidified withstructural agents such as waxes.

[0005] For the purposes of the invention, the expression “liquid fattyphase” means a fatty phase which is liquid at room temperature (25° C.)and atmospheric pressure (760 mmHg, i.e 101 KPa), and comprises at leastone (as used throughout herein, the expression “at least one” means oneor more and thus includes individual components as well asmixtures/combinations) fatty substance that is liquid at roomtemperature, also referred to as an oil, that is generally mutuallycompatible, i.e. forming a homogeneous phase macroscopically. Theexpression “liquid fatty substance” means a non-aqueous liquid mediumwhich is immiscible in all proportions with water, for example, ahydrocarbon-based compound comprising at least one carbon chaincontaining at least 5 carbon atoms and possibly comprising at least onepolar group chosen from carboxylic acid, hydroxyl, polyol, amine, amide,phosphoric acid, phosphate, ester, ether, urea, carbamate, thiol,thioether and thioester, a silicone compound optionally comprisingcarbon chains at the end or pendant, these chains optionally beingsubstituted with a group chosen from fluoro, perfluoro, (poly)aminoacid, ether, hydroxyl, amine, acid and ester groups; or a fluoro orperfluoro compound such as fluorohydrocarbons or perfluorohydrocarbonscontaining at least 5 carbon atoms, possibly comprising a hetero atomchosen from N, O, S and P and optionally at least one polar functionchosen from ether, ester, amine, acid, carbamate, urea, thiol andhydroxyl groups. In practice, the total liquid fatty phase may bepresent, for example, in an amount ranging from 1% to 99% by weightrelative to the total weight of the composition; further examplesinclude ranges of 5% to 99%, 5% to 95.5%, 10% to 80%, and 20% to 75%.

[0006] For the purposes of the present invention, the term “wax” means alipophilic fatty compound that is solid at room temperature (25° C.) andatmospheric pressure (760 mmHg, i.e. 101 KPa), which undergoes areversible solid/liquid change of state, having a melting point ofgreater than 40° C., for example greater than 55° C., such as up to 200°C., and having an anisotropic crystal organization in the solid state.The size of the crystals may be such that the crystals diffract and/orscatter light, giving the composition a cloudy, more or less opaqueappearance. By bringing the wax to its melting point, it is possible tomake it miscible with oils and to form a microscopically homogeneousmixture, but on returning the temperature of the mixture to roomtemperature, recrystallization of the wax in the oils of the mixture isobtained, this recrystallization being responsible for therigidification of the liquid fatty phase.

[0007] For the purposes of the invention, the waxes are those generallyused in cosmetics and dermatology; they are, for instance, chosen fromwaxes of natural origin, such as beeswax, carnauba wax, candelilla wax,ouricury wax, Japan wax, cork fibre wax, sugar cane wax, paraffin wax,lignite wax, microcrystalline waxes, lanolin wax, montan wax, ozokeritesand hydrogenated oils such as hydrogenated jojoba oil, as well as waxesof synthetic origin, for instance polyethylene waxes derived from thepolymerization or copolymerization of ethylene, waxes obtained byFischer-Tropsch synthesis, fatty acid esters and glycerides that aresolid at 40° C., for example at above 55° C., silicone waxes such asalkyl- and alkoxy-poly(di)methylsiloxanes and/or poly(di)methylsiloxaneesters that are solid at 40° C., for example at above 55° C.

[0008] According to the invention, the melting point values maycorrespond to the melting peak measured by the “Differential ScanningCalorimetry” method with a temperature rise of 5 or 10° C./min.

[0009] Unfortunately, the waxes currently used may give the compositiona greasy and oily feel and/or a greasy and lank sensation. Furthermore,manufacturing a stick with waxes often poses problems of reproducibilityon account of the melting point variability of the various waxes thatare commercially available.

[0010] Now, the structuring of the liquid fatty phase with waxes makesit possible, in addition to obtaining a product in the form of a stick,to limit the exudation of the fatty phase from the solid compositions,especially in hot and humid regions, and to limit, after deposition onthe skin or the lips, the migration of this phase in the wrinkles andfine lines, which is particularly sought after for a lipstick, aconcealer product or an eyeshadow. Specifically, large migration of theliquid fatty phase, in particular when it is charged with coloringagents, may lead to an unpleasant appearance around the lips and theeyes, which particularly makes the wrinkles and fine lines moreprominent. This migration is often mentioned by consumers as being amajor defect of conventional lipsticks, concealer products and eyemake-ups in stick form. The term “migration” means a running of thecomposition beyond the initial application line.

[0011] The structuring of the liquid fatty phase and the limitation ofits exudation and of the migration of the deposit on the skin or thelips may increase as the wax content increases. Thus, the content ofthese structuring agents may be a constraining factor on the comfort,reproducibility, non greasy sensation and lightness of make-up productsin stick form.

[0012] Furthermore, make-up compositions should have good staying poweror long wearing properties over time and in particular of the color.Poor staying power is characterized by a color change (turning, fading)or a non-uniform change in the make-up effect over time, generallyfollowing an interaction with sebum and/or sweat secreted by the skin,and, for the lips, an interaction with saliva. Specifically, acomposition which does not have good staying power or long-wearingproperties over time may oblige the user to reapply the make-upregularly. However, consumers nowadays wish to enhance the beauty oftheir face or body while spending as little time as possible in doingso.

[0013] To overcome at least one of these drawbacks, the presentinventors have envisaged replacing all or some of the waxes withpolymers for structuring the liquid fatty phase, for example, of thepolyamide, polyurea or polyurethane type. Unfortunately, the sticksobtained may have a greater or lesser tendency to exude, in particularin a hot and humid environment, and/or to become brittle when applied tothe lips or the skin. This embrittlement may be reflected by breakage ofthe stick, during its shear on application.

[0014] Furthermore, the majority of make-up or care compositions, whenapplied to the skin, the eyelashes or the lips, may have the drawback oftransferring, i.e., of being at least partly deposited and leaving markson certain supports with which they may come into contact, such as aglass, a cup, a cigarette, an item of clothing or the skin. This mayresult in mediocre persistence of the film applied, making it necessaryto reapply the composition regularly, such as a foundation or alipstick. However, as noted above, users nowadays wish to achieve beautyenhancement of their face, including the lips, and their body whilespending as little time as possible in doing so. Moreover, theappearance of these unacceptable marks, e.g., on shirt collars, can putcertain consumers off using this type of make-up.

[0015] Cosmeticians have been interested in “transfer-resistant”lipstick compositions for several years, and more recently in“transfer-resistant” foundation compositions. Thus, in its patentapplication JP-A-61-65809, the company Shiseido envisaged“transfer-resistant” lipstick compositions containing a siloxysilicateresin (with a three-dimensional network), a volatile silicone oilcontaining a cyclic silicone chain and pulverulent fillers. Similarly,in document JP-A-62-61911, the company Noevier disclosed“transfer-resistant” lipstick, eyeliner and foundation compositionscomprising one or more volatile silicones combined with one or morehydrocarbon-based waxes.

[0016] Although these compositions have improved “transfer-resistance”properties, they have the drawback of leaving on the lips, after thesilicone oils have evaporated off, a film which becomes uncomfortableover time (sensation of drying out the lips and of tautness), acharacteristic which puts a certain number of consumers off using thistype of lipstick.

[0017] The need thus remains for a composition which does not have atleast one of the above drawbacks, for example, which has at least one ofgood mechanical and thermal stability over time, even in hot and humidcountries, and which produces a deposit on the skin or the lips that hasat least one of the following characteristics: shows good staying powerover time, does not migrate, and does not transfer. Furthermore, thiscomposition should be easy to manufacture and, in an embodiment of theinvention, gives the deposit at least one of a comfortable andnon-greasy sensation, both during application and over time.

[0018] Accordingly, in one aspect, the present invention is drawn to acare and/or make-up and/or treatment composition for the skin and/or thelips of the face and/or for superficial body growths, such as nails orkeratinous fibres, such as hair, which may make it possible to overcomeat least one of the drawbacks mentioned above. It is to be noted that adeodorant product is a body hygiene product and does not relate to care,make-up or treatment of keratin materials, including keratinous fibers,skin, or lips.

[0019] The inventors have found, surprisingly, that the use of specificpolymers combined with at least one filler may make it possible toobtain a composition in rigid form such as a stick, whose application tothe skin or the lips produces a deposit which has noteworthy cosmeticproperties. For example, the deposit may be at least one of supple,comfortable, light and “migration-resistant”. In addition, in thepresence of volatile solvent, the composition may show goodtransfer-resistance properties.

[0020] Moreover, the composition may be stable over time, may withstandshear during application and may not exude at room temperature or atelevated temperature (40 to 47° C. approximately); it can be heatstable. In addition, it can have a pleasant, fondant texture and canslide easily on the skin or the lips without being greasy.

[0021] The expression “heat stable” means a composition which does notexude at room temperature for at least 2 months, such as, for example,for at least 9 months, or at 37° C. or at 47° C. for one month.

[0022] The invention applies not only to make-up products for the lips,such as lipsticks, lip glosses and lip pencils, but also to care and/ortreatment products for the skin, including the scalp, and for the lips,such as antisun products, for example in stick form for facial skin orthe lips, care products for the human face or body, make-up products forthe skin, both of the human face and body, such as foundationsoptionally cast in stick or dish form, concealer products, blushers,make-up removing, eyeshadows, face powders, transfer tattoos, bodyhygiene products such as deodorants, e.g., in stick form, shampoos,conditioners and make-up products for the eyes such as eyeliners, eyepencils and mascaras, e.g., in cake form, as well as make-up and careproducts for superficial body growths, for instance keratinous fiberssuch as the hair, the eyelashes and the eyebrows, or nails.

[0023] More specifically, the present invention is drawn to acomposition containing at least one liquid fatty which comprises atleast one structuring polymer comprising a polymer skeleton whichcomprises at least one hydrocarbon-based repeating unit comprising atleast one hetero atom.

[0024] The at least one liquid fatty phase further contains at least oneinert filler. The at least one liquid fatty phase, the at least onestructuring polymer and the at least one inert filler form aphysiologically acceptable medium.

[0025] In one embodiment, the at least one structuring polymer has aweight-average molecular mass of less than 100 000. However, thisweight-average molecular mass can represent up to 500 000 and even up to1 000 000.

[0026] In one aspect, the present invention is drawn to a structuredcomposition containing at least one liquid fatty phase structured withat least one structuring polymer comprising a polymer skeletoncomprising at least one hydrocarbon-based repeating unit comprising atleast one hetero atom. In one embodiment, the at least one structuringpolymer further comprises at least one terminal fatty chain, optionallyfunctionalized, comprising at least one chain chosen from alkyl andalkenyl chains, such as alkyl and alkenyl chains comprising at least 4carbons atoms, and further such as alkyl and alkeny chains comprisingfrom 8 to 120 carbon atoms, bonded to the polymer skeleton via at leastone linking group. The at least one structuring polymer may also furthercomprise at least one pendant fatty chain, optionally functionalized,comprising at least one chain chosen from alkyl and alkenyl chains, suchas alkyl and alkenyl chains comprising at least 4 carbons atoms, andfurther such as alkyl and alkeny chains comprising from 8 to 120 carbonatoms, bonded to any carbon or hetero atom of the polymer skeleton viaat least one linking group. The at least one structuring polymer maycomprise both at least one pendant fatty chain and at least one terminalfatty chain as defined above. The at least one liquid fatty phasefurther contains at least one inert filler. The at least one liquidfatty phase, the at least one structuring polymer and the at least oneinert filler form a physiologically acceptable medium.

[0027] The composition of the invention can be in the form of a paste, asolid or a more or less viscous cream. It can be a single or multipleemulsion, such as an oil-in-water or water-in-oil emulsion or anoil-in-water-in-oil emulsion, or a rigid or soft gel containing an oilycontinuous phase. For example, the liquid fatty phase can be thecontinuous phase of the composition. In one embodiment, the compositionis anhydrous. In one embodiment, the composition is in a form cast as astick or in a dish, for example, solid and further example in the formof an oily rigid gel, such as an anhydrous gel, e.g., an anhydrousstick. In a further embodiment, the composition is in the form of anopaque or translucent rigid gel (depending on the presence or absence ofpigments), and in a specific example, the liquid fatty phase forms thecontinuous phase. In One embodiment, the composition is chosen frommolded and poured sticks.

[0028] The structuring of the liquid fatty phase can be modifiedaccording to the nature of the polymer containing a hetero atom and ofthe inert filler used, and may be such that a rigid structure in theform of a stick with good mechanical strength is obtained. When thesesticks are colored, they may make it possible, after application, toobtain a uniformly colored glossy deposit which does not migrate andwhich has good staying power or long-wearing properties, in particularof the color, over time.

[0029] The composition of the invention may, for example, be acomposition for the skin or the lips, such as a foundation composition,concealer product, eyeshadow or lipstick composition, e.g., in stickform.

[0030] Structuring Polymer

[0031] In one embodiment, the at least one structuring polymer in thecomposition of the invention is a solid that is not deformable at roomtemperature (25° C.) and atmospheric pressure (760 mmHg, i.e. 101 KPa).In a further embodiment, the at least one structuring polymer is capableof structuring the composition without opacifying it. The inventorsthink that is due to the fact that the polymer does not crystallise.Moreover, the structuration of the liquid fatty phase is due to hydrogeninteractions between two molecules of polymer and/or between the polymerand the liquid fatty phase. As defined above, the at least onestructuring polymer of the present invention comprises a polymerskeleton comprising at least one hydrocarbon-based repeating unitcomprising at least one hetero atom. In one embodiment, the at least onestructuring polymer further comprises at least one terminal fatty chainchosen from alkyl and alkenyl chains, such as of at least 4 atoms, andfurther such as comprising 8 to 120 carbon atoms, bonded to the polymerskeleton via at least one linking group. The terminal fatty chain may,for example, be functionalized. The at least one structuring polymer mayalso further comprise at least one pendant fatty chain chosen from alkyland alkenyl chains, such as of at least 4 atoms, and further such ascomprising 8 to 120 carbon atoms, bonded to any carbon or hetero atom ofthe polymer skeleton via at least one linking group. The pendant fattychain may, for example, be functionalized. The at least one structuringpolymer may comprise both at least one pendant fatty chain and at leastone terminal fatty chain as defined above, and one or both types ofchains can be functionalized.

[0032] In one embodiment, the structuring polymer comprises at least twohydrocarbon-based repeating units. As a further example, the structuringpolymer comprises at least three hydrocarbon-based repeating units andas an even further example, the at least three repeating units areidentical.

[0033] As used herein, “functionalized” means comprising at least onefunctional group. Non-limiting examples of functional groups includehydroxyl groups, ether groups, oxyalkylene groups, polyoxyalkylenegroups, carboxylic acid groups, amine groups, amide groups, halogencontaining groups, including fluoro and perfluoro groups, halogen atoms,ester groups, siloxane groups and polysiloxane groups.

[0034] For purposes of the invention, the expression “functionalizedchain” means, for example, an alkyl chain comprising at least onefunctional (reactive) group chosen, for example, from those recitedabove. For example, in one embodiment, the hydrogen atoms of at leastone alkyl chain may be substituted at least partially with fluorineatoms.

[0035] According to the invention, these chains may be linked directlyto the polymer skeleton or via an ester function or a perfluoro group.

[0036] For the purposes of the invention, the term “polymer” means acompound containing at least 2 repeating units, such as, for example, acompound containing at least 3 repeating units, which may be identical.

[0037] As used herein, the expression “hydrocarbon-based repeating unit”includes a repeating unit comprising from 2 to 80 carbon atoms, such as,for example, from 2 to 60 carbon atoms. The at least onehydrocarbon-based repeating unit may also comprise oxygen atoms. Thehydrocarbon-based repeating unit may be chosen from saturated andunsaturated hydrocarbon-based repeating units which in turn may bechosen from linear hydrocarbon-based repeating units, branchedhydrocarbon-based repeating units and cyclic hydrocarbon-based repeatingunits. The at least one hydrocarbon-based repeating unit may comprise,for example, at least one hetero atom that is part of the polymerskeleton, i.e., not pendant. The at least one hetero atom may be chosen,for example, from nitrogen, sulphur, and phosphorus. For example, the atleast one hetero atom may be a nitrogen atom, such as a non-pendantnitrogen atom. In another embodiment, the at least one hydrocarbon-basedrepeating unit may comprise at least one hetero atom with the provisothat the at least one hetero atom is not nitrogen. In anotherembodiment, the at least one hetero atom is combined with at least oneatom chosen from oxygen and carbon to form a hetero atom group. In oneembodiment, the hetero atom group comprises a carbonyl group.

[0038] The at least one repeating unit comprising at least one heteroatom may be chosen, for example, from amide groups, carbamate groups,and urea groups. In one embodiment, the at least one repeating unitcomprises amide groups forming a polyamide skeleton. In anotherembodiment, the at least one repeating unit comprises carbamate groupsand/or urea groups forming a polyurethane skeleton, a polyurea skeletonand/or a polyurethane-polyurea skeleton. The pendant chains, forexample, can be linked directly to at least one of the hetero atoms ofthe polymer skeleton. In yet another embodiment, the at least onehydrocarbon-based repeating unit may comprise at least one hetero atomgroup with the proviso that the at least one hetero atom group is not anamide group. In one embodiment, the polymer skeleton comprises at leastone repeating unit chosen from silicone units and oxyalkylene units, theat least one repeating unit being between the hydrocarbon-basedrepeating units.

[0039] In one embodiment, the composition of the invention comprises atleast one structuring polymer with nitrogen atoms, such as amide, urea,or carbamate units, such as amide units, and at least one polar oil.

[0040] In one embodiment, in the at least one structuring polymer, thepercentage of the total number of fatty chains ranges from 40% to 98%relative to the total number of repeating units and fatty chains, and asa further example, from 50% to 95%. In a further embodiment wherein thepolymer skeleton is a polyamide skeleton, in the at least onestructuring polymer, the percentage of the total number of fatty chainsranges from 40% to 98% relative to the total number of all amide unitsand fatty chains, and as a further example, from 50% to 95%.

[0041] In a further embodiment, the nature and proportion of the atleast one hydrocarbon-based repeating unit comprising at least onehetero atom depends on the nature of a liquid fatty phase of thecomposition and is, for example, similar to the nature of the fattyphase. For example, not to be limited as to theory, the more polar thehydrocarbon-based repeating units containing a hetero atom, and in highproportion, which corresponds to the presence of several hetero atoms,the greater the affinity of the at least one structuring polymer topolar oils. Conversely, the more non-polar, or even apolar, and lesserin proportion the hydrocarbon-based repeating units containing a heteroatom, the greater the affinity of the polymer for apolar oils.

[0042] In another embodiment, the invention is drawn to a structuredcomposition containing at least one liquid fatty phase structured withat least one structuring polymer, wherein said at least one structuringpolymer is a polyamide comprising a polymer skeleton comprising at leastone amide repeating unit and optionally at least one pendant fatty chainand/or at least one terminal chain that are optionally functionalizedand comprising at least one chain chosen from alkyl and alkenyl chains,such as alkyl and alkenyl chains comprising at least 4 carbons atoms,and further such as alkyl and alkeny chains comprising from 8 to 120carbon atoms, bonded to at least one of the amide repeating units via atleast one linking group. The liquid fatty phase further contains atleast one inert filler for thickening the liquid fatty phase. The atleast one liquid fatty phase, the at least one structuring polyamide andthe at least one inert filler together form a physiologically acceptablemedium.

[0043] When the structuring polymer has amide repeating units, thependant fatty chains may be linked to at least one of the nitrogen atomsin the amide repeating units.

[0044] The structuring polymer, for example the polyamide polymer, mayhave a weight-average molecular mass of less than 100,000, such as lessthan 50,000. In another embodiment, the weight-average molecular massmay range from 1000 to 30,000, such as from 2000 to 20,000, further suchas from 2000 to 10,000.

[0045] The structuring polymer, as form example the polyamide polymer,is non soluble in water or in aqueous phase. In another embodiment thestructuring polymer has non ionic group.

[0046] As discussed, the at least one structuring polymer may, forexample, be chosen from polyamide polymers. A polyamide polymer maycomprise, for example, a polymer skeleton which comprises at least oneamide repeating unit, i.e., a polyamide skeleton. In one embodiment, thepolyamide skeleton may further comprise at least one terminal fattychain chosen from alkyl chains, for example, alkyl chains comprising atleast four carbon atoms, and alkenyl chains, for example, alkenyl chainscomprising at least four carbon atoms, bonded to the at least onepolyamide skeleton via at least one linking group, and/or at least onependant fatty chain chosen from alkyl chains, for example, alkyl chainscomprising at least four carbon atoms, and alkenyl chains, for example,alkenyl chains comprising at least four carbon atoms, bonded to the atleast one polyamide skeleton via at least one linking group. In oneembodiment, the polyamide skeleton may comprise at least one terminalfatty chain chosen from fatty chains comprising 8 to 120 carbon atoms,such as, for example, 12 to 68 carbon atoms, bonded to the at least onepolyamide skeleton via at least one linking group and/or at least onependant fatty chain chosen from fatty chains comprising 8 to 120 carbonatoms, such as, for example, 12 to 68 carbon atoms, bonded to the atleast one polyamide skeleton via at least one linking group, such asbonded to any carbon or nitrogen of the polyamide skeleton via said atleast one linking group. In one embodiment, the at least one linkinggroup is chosen from single bonds and urea, urethane, thiourea,thiourethane, thioether, thioester, ester, ether and amine groups. Inanother embodiment, the linking groups are chosen from ureas, esters,and amines, and as a further example, from esters and amines. The bondis, for example, an ester bond. In one embodiment, these polymerscomprise a fatty chain at each end of the polymer skeleton, such as thepolyamide skeleton.

[0047] In one embodiment, due to the presence of at least one chain, thepolyamide polymers may be readily soluble in oils (i.e.,water-immiscible liquid compounds) and thus may give macroscopicallyhomogeneous compositions even with a high content (at least 25%) of thepolyamide polymers, unlike certain polymers of the prior art that do notcontain such alkyl or alkenyl chains at the end of the polyamideskeleton. As defined herein, a composition is soluble if it has asolubility of greater than 0.01 g per 100 ml of solution at 25° C.

[0048] In a further embodiment, the polyamide polymers can be chosenfrom polymers resulting from at least one polycondensation reactionbetween at least one acid chosen from dicarboxylic acids comprising atleast 32 carbon atoms, such as 32 to 44 carbon atoms, and at least oneamine chosen from diamines comprising at least 2 carbon atoms, such asfrom 2 to 36 carbon atoms, and triamines comprising at least 2 carbonatoms, such as from 2 to 36 carbon atoms. The at least one dicarboxylicacid can, for example, be chosen from dimers of at least one fatty acidcomprising at least 16 carbon atoms, such as oleic acid, linoleic acidand linolenic acid. The at least one amine can, for example, be chosenfrom diamines, such as ethylenediamine, hexylenediamine,hexamethylenediamine, phenylenediamine and triamines, such asethylenetriamine.

[0049] The polyamide polymers may also be chosen from polymerscomprising at least one terminal carboxylic acid group. The at least oneterminal carboxylic acid group can, for example, be esterified with atleast one alcohol chosen from monoalcohols comprising at least 4 carbonatoms. For example, the at least one alcohol can be chosen frommonoalcohols comprising from 10 to 36 carbon atoms. In a furtherembodiment, the monoalcohols can comprise from 12 to 24 carbon atoms,such as from 16 to 24 carbon atoms, and for example 18 carbon atoms.

[0050] In one embodiment, the at least one polyamide polymer may bechosen from those described in U.S. Pat. No. 5,783,657, the disclosureof which is incorporated herein by reference, which are polyamidepolymers of formula (I):

[0051] in which:

[0052] n is an integer which represents the number of amide units suchthat the number of ester groups present in said at least one polyamidepolymer ranges from 10% to 50% of the total number of all said estergroups and all said amide groups comprised in the at least one polyamidepolymer;

[0053] R¹, which are identical or different, are each chosen from alkylgroups comprising at least 4 carbon atoms and alkenyl groups comprisingat least 4 carbon atoms. In one embodiment, the alkyl group comprisesfrom 4 to 24 carbon atoms and the alkenyl group comprises from 4 to 24carbon atoms;

[0057] In the polymer of formula (I), the terminal fatty chains that areoptionally functionalized for the purposes of the invention are terminalchains linked to the last hetero atom, in this case nitrogen, of thepolyamide skeleton.

[0058] In one embodiment, the ester groups of formula (I), which formpart of the terminal and/or pendant fatty chains for the purposes of theinvention, are present in an amount ranging from 15% to 40% of the totalnumber of ester and amide groups (i.e. hetero atom groups), such as from20% to 35%.

[0059] In formula (I), in one embodiment, n may be an integer rangingfrom 1 to 10, from example from 1 to 5, and as further for example aninteger ranging from 3 to 5. In the present invention, R¹, which areidentical or different, can, for example, each be chosen from C₁₂ to C₂₂alkyl groups, such as from C₁₆ to C₂₂ alkyl groups.

[0060] In the present invention, R², which are identical or different,can, for example, each be chosen from C₁₀ to C₄₂ hydrocarbon-based,e.g., alkylene groups. At least 50% of all R², for example at least 75%of all R², which are identical or different, can, for example, each bechosen from groups comprising from 30 to 42 carbon atoms. In the twoaforementioned embodiments, the remaining R², which are identical ordifferent, can, for example, each be chosen from C₄ to C₁₈ groups, suchas C₄ to C₁₂ groups.

[0061] R³, which can be identical or different, can, for example, eachbe chosen from C₂ to C₃₆ hydrocarbon-based groups and polyoxyalkylenegroups. In another example, R³, which can be identical or different, caneach, for example, be chosen from C₂ to C₁₂ hydrocarbon-based groups. Inanother embodiment, R⁴, which can be identical or different, can each bechosen from hydrogen atoms.

[0062] As used herein, hydrocarbon-based groups may be chosen fromlinear, cyclic and branched, and saturated and unsaturated groups. Thehydrocarbon-based groups can be chosen from aliphatic and aromaticgroups. In one example, the hydrocarbon-based groups are chosen fromaliphatic groups. The alkyl and alkylene groups may be chosen fromlinear, cyclic and branched, and saturated and unsaturated groups.

[0063] In general, the pendant and terminal fatty chains may be chosenfrom linear, cyclic and branched, and saturated and unsaturated groups.The pendant and terminal fatty chains can be chosen from aliphatic andaromatic groups. In one example, the pendant and terminal fatty chainsare chosen from aliphatic groups.

These are sold, respectively, inthe form of an 80% (in terms of active material) gel in a mineral oiland a 100% (in terms of active material) gel. These polymers have asoftening point ranging from 88° C. to 94° C., and may be mixtures ofcopolymers derived from monomers of (i) C₃₆ diacids and (ii)ethylenediamine, and have a weight-average molecular mass of about 6000.Terminal ester groups result from esterification of the remaining acidend groups with at least one alcohol chosen from cetyl alcohol andstearyl alcohol. A mixture of cetyl and stearyl alcohols is sometimescalled cetylstearyl alcohol.

Thissoftening point may be lower than that of structuring polymers used inthe art which may facilitate the use of the at least one structuringpolymer of the present invention and may limit the degradation of theliquid fatty phase. These polymers may be non waxy polymers. Thesoftening point can be measured by a well known method as DifferentialScanning Calorimetry (i.e. DSC method) with a temperature rise of 5 to10° C./min.

[0070] In one embodiment, the at least one structuring polymer in thecomposition according to the invention corresponds to the polyamidepolymers of formula (I).

[0078] Additionally, an embodiment of the invention relates to a skin,lip, or keratinous fiber care or make-up composition comprising astructured composition containing at least one liquid fatty phasestructured with at least one structuring polymer comprising a polymerskeleton comprising at least one hydrocarbon-based repeating unitcomprising at least one hetero atom, at least one inert filler, and atleast one coloring agent.

[0080] Inert Filler

[0081] According to the invention, the composition contains at least oneinert filler. The term “filler” means any particle that is solid at roomtemperature and atmospheric pressure, used alone or in combination,which does not react chemically with the various ingredients of thecomposition and which is insoluble in these ingredients, even when theseingredients are raised to a temperature above room temperature and inparticular to their softening point or their melting point.

[0082] The at least one inert filler has a melting point at leastgreater than 150° C., for example greater than 170° C. and further asfor example, greater than 200° C. The at least one inert filler may ormay not be absorbent, i.e., capable in particular of absorbing the oilsof the composition and also the biological substances secreted by theskin. The absorbent fillers often have the property of making thedeposit of composition on the keratin materials matte, which isparticularly desired for a foundation and a concealer product. In oneembodiment, the at least one inert filler may have an apparent diameterranging from 0.01 μm to 150 μm, such as from 0.5 μm to 120 μm, forexample from 1 μm to 80 μm. An apparent diameter corresponds to thediameter of the circle into which the elementary particle fits along itsshortest dimension (thickness for leaflets).

[0083] The at least one inert filler may be present in the inventivecomposition in an amount ranging from 0.1% to 40% relative to the weightof the total composition, such as from 2% to 30%, and, for example, from5% to 20%.

[0084] The at least one inert filler may be mineral or organic, andlamellar, spherical or oblong. The at least one inert filler may bechosen from talc, mica, silica, kaolin, polyamide powders such as Nylon®(Orgasol® from Atochem) powder, poly-β-alanine powder, polyethylenepowder, acrylic polymer powder and in particular polymethyl methacrylate(PMMA) powder, for instance the product sold or made by Wacker under thereference Covabead LH-85 (particle size 10-12 μm) or acrylic acidcopolymer powder (Polytrap® from Dow Corning), polytetrafluoroethylene(Teflon®) powders, lauroyllysine, boron nitride, starch, hollow polymermicrospheres such as those of polyvinylidene chloride/acrylonitrile, forinstance Expancel® (Nobel Industrie), hollow polymer microspheres(Tospearl® from Toshiba, for example), precipitated calcium carbonate,magnesium carbonate and hydrocarbonate, hydroxyapatite, hollow silicamicrospheres (Silica Beads® from Maprecos), glass or ceramicmicrocapsules and polyester particles. The at least one inert filler maybe surface-treated, e.g., to make them lipophilic.

[0085] The at least one inert filler may be porous so as to absorb thesweat and/or sebum secreted by the skin. Such inert fillers includesilica, polyethylene powder, polyamide (Nylon®) powder, kaolin, starchderivatives and Polytrap®.

[0086] In order to minimize the exudation of the composition in castform, the at least one inert filler used in the composition may containa chemical group of the same chemical nature as those of the units ofthe structuring polymer or a chemical group capable of forming physicalbonds of the same type as that of the units of the polymer (for example,chosen from self-complementary hydrogen bonds, π interactions betweenunsaturated rings or filler-transfer interactions, dipolar interactions,and coordination bonds with organometallic derivatives). Thus, forstructuring polymers containing units of the amide, urea and/or urethanetype, the at least one inert filler used may contain groups capable offorming hydrogen bonds, like these structuring polymers. As fillerscapable of forming hydrogen bonds, mention may be made of fillers orparticles of acrylic polymer such as PMMA for instance the product soldby Wacker under the reference Covabead LH-85 (particle size 10-12 μm)and Polytrap® sold or made by Dow Corning, hydrophobic-treated silica,polyamide (Nylon®) powders (Orgasol® from Atochem), and mixturesthereof. For units of the ester type, the fillers used may be of thepolyester type.

[0087] The surface of the silica may be chemically modified, byhydrophobic chemical treatments, giving rise to a decrease in the numberof silanol groups. The hydrophobic groups may be:

[0088] trimethylsiloxyl groups, which are obtained, for example, bytreating fumed silica in the presence of hexamethyidisilazane. Silicasthus treated are known as “silica silylate” according to the CTFA (6thedition, 1995). They are sold, or made for example, under the references“Aerosil R812®” by the company Degussa and “CAB-O-SIL TS-530®” by thecompany Cabot;

[0089] dimethylsilyloxyl or polydimethylsiloxane groups, which areobtained, for example, by treating fumed silica in the presence ofpolydimethylsiloxane or dimethyidichlorosilane. Silicas thus treated areknown as “silica dimethyl silylate” according to the CTFA (6th edition,1995). They are made or sold, for example, under the references “AerosilR972®” and “Aerosil R974®” by the company Degussa, and “CAB-O-SILTS-610®” and “CAB-O-SIL TS-720®” by the company Cabot;

[0090] groups derived from reacting fumed silica with silane alkoxidesor siloxanes. These treated silicas are, for example, the products madeor sold under the reference “Aerosil R805®” by the company Degussa.

[0091] According to the invention, a hydrophobic silica, such as a fumedsilica, may be used as lipophilic gelling agent or rheological agent.The use of fumed silica may make it possible to obtain a translucent oreven transparent composition, in particular in the form of a stick whichdoes not exude, in the absence of opacifying particles such as waxes,fillers and pigments (including nacres).

[0092] In one embodiment, the filler is lipophilic or traited to belipophilic.

[0093] Amphiphilic Compound

[0094] The at least one structuring polymer and the at least one inertfiller can be combined with at least one amphiphilic compound that isliquid and non-volatile at room temperature and has ahydrophilic/lipophilic balance (HLB) value of less than 12, for exampleranging from 1 to 8 or from 1 to 5. These amphiphilic compounds may actto reinforce the structuring properties of the polymer containing atleast one hetero atom, to facilitate the implementation of the polymerand to improve the ability of the stick to be deposited. However, it ispossible to obtain a stick with good mechanical and/or thermalproperties without including at least one amphiphilic compound.

[0095] Depending on the intended application, such as a stick, hardnessof the composition may also be considered. The hardness of a compositionmay, for example, be expressed in gramforce (gf). The composition of thepresent invention may, for example, have a hardness ranging from 20 gfto 2000 gf, such as from 20 gf to 900 gf, and further such as from 20 gfto 600 gf.

[0096] This hardness is measured in one of two ways. A first test forhardness is according to a method of penetrating a probe into saidcomposition and in particular using a texture analyzer (for exampleTA-XT2i from Rheo) equipped with an ebonite cylinder of height 25 mm anddiameter 8 mm. The hardness measurement is carried out at 20° C. at thecenter of 5 samples of said composition. The cylinder is introduced intoeach sample of composition at a pre-speed of 2 mm/s and then at a speedof 0.5 mm/s and finally at a post-speed of 2 mm/s, the totaldisplacement being 1 mm. The recorded hardness value is that of themaximum peak observed. The measurement error is ±50 gf.

[0097] The second test for hardness is the “cheese wire” method, whichinvolves cutting an 8.1 mm or preferably 12.7 mm in diameter stick ofcomposition and measuring its hardness at 20° C. using a DFGHS 2 tensiletesting machine from Indelco-Chatillon Co. at a speed of 100 mm/minute.The hardness value from this method is expressed in grams as the shearforce required to cut a stick under the above conditions. According tothis method, the hardness of compositions according to the presentinvention which may be in stick form may, for example, range from 30 gfto 300 gf, such as from 30 gf to 250 gf, and further such as from 30 gfto 200 gf.

[0098] The hardness of the composition of the present invention may besuch that the compositions are self-supporting and can easilydisintegrate to form a satisfactory deposit on a keratinous material. Inaddition, this hardness may impart good impact strength to the inventivecompositions which may be molded or cast, for example, in stick or dishform. The composition of the invention may be a solid, in the form ofmolded or poured sticks.

[0099] The skilled artisan may choose to evaluate a composition using atleast one of the tests for hardness outlined above based on theapplication envisaged and the hardness desired. If one obtains anacceptable hardness value, in view of the intended application, from atleast one of these hardness tests, the composition falls within thescope of the invention.

[0100] As is evident, the hardness of the composition according to theinvention may, for example, be such that the composition isadvantageously self-supporting and can disintegrate easily to form asatisfactory deposit on the skin and/or the lips and/or superficial bodygrowths, such as keratinous fibres. In addition, with this hardness, thecomposition of the invention may have good impact strength.

[0101] According to the invention, the composition in stick form mayhave the behavior of a deformable, flexible elastic solid, givingnoteworthy elastic softness on application. The compositions in stickform of the prior art do not have these properties of elasticity andflexibility.

[0102] The at least one amphiphilic compound which can be used in thecomposition of the invention may, for example, comprise a lipophilicpart linked to a polar part, the lipophilic part comprising acarbon-based chain containing at least 8 carbon atoms, for example from18 to 32 carbon atoms or from 18 to 28 carbon atoms. The polar part ofthe at least one amphiphilic compound may, in one embodiment, be theresidue of a compound chosen from alcohols and polyols containing from 1to 12 hydroxyl groups, and polyoxyalkylenes comprising at least 2oxyalkylene units and containing from 0 to 20 oxypropylene units and/orfrom 0 to 20 oxyethylene units. For example, the at least oneamphiphilic compound may be an ester chosen from the hydroxystearates,oleates and isostearates of glycerol, of sorbitan and of methylglucose,and from branched C₁₂ to C₂₆ fatty alcohols such as octyldodecanol.Among these esters, monoesters and mixtures of mono- and diesters canalso be used.

[0103] The respective contents of the at least one lipophilic inertfiller, the at least one polymer containing a hetero atom and optionallythat of at least one amphiphilic compound are chosen according to thedesired hardness of the composition and as a function of the specificapplication envisaged. The respective amounts of polymer, of inertfiller and of amphiphilic compound should be such that they produce astick which can be worn down. In practice, the amount of the at leastone polymer may be chosen from 0.5% to 80% of the total weight of thecomposition, for example from 2% to 60%, from 5% to 40%, and from 5% to25%. The amount of at least one amphiphilic compound in practice, if itis present, may be chosen from 0.1% to 35% of the total weight of thecomposition, for example from 1% to 20% or from 1% to 15%.

[0104] The at least one structuring polymer has an affinity with thefatty phase and in particular with a chemical portion of one of the oilsforming the liquid fatty phase of the composition so that physical linkswith the oils, such as hydrogen bonds, or as above-mentioned, areformed.

[0105] Liquid Fatty Phase

[0106] The at least one liquid fatty phase, in one embodiment, maycomprise at least one oil. In one embodiment, at least one oil has anaffinity with the structuring polymer. The at least one oil, forexample, may be chosen from polar oils and apolar oils includinghydrocarbon-based liquid oils and oily liquids at room temperature. Inone embodiment, the composition of the invention comprises at least onestructuring polymer and at least one polar oil. The polar oils of theinvention, for example, may be added to the apolar oils, the apolar oilsacting in particular as co-solvent for the polar oils.

[0107] According to the invention, the structuring of the at least oneliquid fatty phase may be obtained with the aid of at least onestructuring polymer, such as the polymer of formula (I). In general, thepolymers of formula (I) may be in the form of mixtures of polymers,these mixtures also possibly containing a synthetic productcorresponding to a compound of formula (I) in which n is 0, i.e., adiester.

[0108] The liquid fatty phase of the composition may contain more than30%, for example, more than 40%, of liquid oil(s) having a chemicalnature close to the chemical nature of the skeleton (hydrocarbon orsilicone based) of the structuring polymer, and for example from 50% to100%. In one embodiment, the liquid fatty phase structured with apolyamide-type skeleton, or polyurea, or polyurethane, orpolyurea-urethane-type skeleton contains a high quantity, i.e., greaterthan 30%, for example greater than 40% relative to the total weight ofthe liquid fatty phase, or from 50% to 100%, of at least one apolar,such as hydrocarbon-based, oil. For the purposes of the invention, theexpression “hydrocarbon-based oil” means an oil comprising carbon andhydrogen atoms, optionally with at least one group chosen from hydroxyl,ester, carboxyl and ether groups.

[0109] For a liquid fatty phase structured with a polymer containing apartially silicone-based skeleton, this fatty phase may contain morethan 30%, for example, more than 40%, relative to the total weight ofthe liquid fatty phase and, for example, from 50% to 100%, of at leastone silicone-based liquid oil, relative to the total weight of theliquid fatty phase.

[0110] For a liquid fatty phase structured with an apolar polymer of thehydrocarbon-based type, this fatty phase may contain more than 30%, forexample more than 40% by weight, and, as a further example, from 50% to100% by weight, of at least one liquid apolar, such ashydrocarbon-based, oil, relative to the total weight of the liquid fattyphase.

[0111] For example, the at least one polar oil useful in the inventionmay be chosen from:

[0118] The liquid fatty phase, in one embodiment, contains at least onenon-volatile oil chosen from, for example, hydrocarbon-based oils ofmineral, plant and synthetic origin, synthetic esters or ethers,silicone oils and mixtures thereof.

[0119] For the purposes of the invention, the expression “volatilesolvent or oil” means any non-aqueous medium capable of evaporating oncontact with the skin or the lips in less than one hour at roomtemperature and atmospheric pressure. The volatile solvent(s) of theinvention is(are) organic solvents, such as volatile cosmetic oils thatare liquid at room temperature, having a non-zero vapor pressure, atroom temperature and atmospheric pressure, ranging in particular from10⁻² to 300 mmHg (1.3 to 40 000 Pa) and, for example, greater than 0.03mmHg (4 Pa) and further example greater than 0.3 mmHg (40 Pa). Theexpression “non-volatile oil” means an oil which remains on the skin orthe lips at room temperature and atmospheric pressure for at leastseveral hours, such as those having a vapor pressure of less than 10⁻²mmHg (1.3 Pa).

[0120] According to the invention, these volatile solvents (or oils) mayfacilitate the staying power or long wearing properties over time andalso the transfer-resistance properties of the composition on the skin,the lips or superficial body growths such as nails and keratinousfibers.

The at least one volatile oil maybe, in one embodiment, chosen from hydrocarbons comprising from 8 to 16carbon atoms.

[0123] The at least one volatile solvent may represent a mass content upto 97.5% relative to the total weight of the .composition, such as from1% to 75% or 10% to 60%, for example from 20% to 60%. In general, the atleast one volatile solvent should be present in an amount that issufficient to obtain transfer-resistance properties and should beadapted by a person skilled in the art as a function of the desiredintensity for these transfer-resistance properties.

EXAMPLE 1Lipstick Phase A Uniclear 100 18% Diisononyl isononanoate  5%Diisostearyl malate 17% Hydrogenated polybutene (Parleam)  4% Phase BHydrophobic silica (Aerosil R972)  3% Hydrogenated polybutene 25%Isononyl isononanoate 12% Phase C Pigments  7% Hydrogenated polybutene 9%

[0275] Procedure

[0276] The Uniclear 100 and the oils of phase A were introduced into aheating vessel. The mixture was placed under magnetic stirring and thenheated in a first stage to 100° C. (to liquefy the Uniclear). A mixturecomprising the silica gel (phase B) prepared beforehand and of theground pigmentary material (phase C), which was heated beforehand to100° C. and homogenized with stirring, was introduced into a heated mold(T°=45° C.). The product obtained was placed, after setting had started,in a freezer (T°=−21° C.) for 15 minutes.

[0277] a) Silica Gel (Phase B)

[0278] The gel was prepared, with stirring in a Rayneri stirrer at 60°C., using a hotplate, by introducing the silica portionwise into theoily mixture formed from Hydrogenated polybutene (Parleam) 25 g Isononylisononanoate 12 g TOTAL 40 g

[0279] b) Ground Pigmentary Material (Phase C)

[0280] The pigments were mixed with the oil heated to 60° C.; themixture was milled 3 times in a three-roll mill.

[0281] The sticks of lipstick had a diameter of 8.1 mm and a hardness of77±10 gf, measured using a “cheese wire” . These lipsticks wereconsidered by testers as having good staying power and being non-greasyand glossy. This lipstick was stable and did not exude at roomtemperature or at 47° C., for 2 months.

[0282] The lipstick obtained deposited a glossy film with good stayingpower. This lipstick was considered by testers as having good stayingpower and being glossy. EXAMPLES 2 TO 4 Cast foundations Severalfoundations differing from each other in the nature of the filler, andhaving the composition below, were prepared: Phase A Uniclear 100   11%Isononyl isononanoate   10% Phase B Coated yellow iron oxide*  2.2%Coated red iron oxide*  0.5% Coated black iron oxide*  0.3% Titaniumoxide*   7% Phase C Filler   10% Phase D Isododecane qs  100%

[0283] Procedure

[0284] The Uniclear 100 was incorporated into the isononyl isononanoate,with the aid of a Rayneri mixer for 10 min., in a heating vessel heatedto 110° C. The stirring was continued until the Uniclear has fullydissolved (phase A).

[0285] In parallel, a pigmentary phase was prepared by incorporating 30g of pigments (iron oxide+titanium oxide) into 8.8 g of isododecane,followed by milling using a three-roll mill. This pigmentary phase(phase B) was then introduced into phase A and the mixture was stirreduntil completely homogeneous, for 30 min., at 110° C. Next, thetemperature was lowered to 95° C. and the volatile phase D was thenadded to the above mixture. After stirring the resulting mixture for 15min., the filler (phase C) was incorporated and stirring of this mixturewas then continued for 20 min. Next, the final mixture obtained was castin foundation molds preheated to 45° C. and the mixture was then left tocool to room temperature (25° C.).

[0286] The fillers used were, respectively, silica beads (Tospearl 145A) (Example 2), Nylon particles (Example 3) and PMMA particles of 10 to12 μm, from Wackherr under the reference Covabead LH-85® (Example 4).With the composition of Example 2, a slight phase separation wasobserved at room temperature after 1 month. With composition 3, goodstability was obtained both at 4° C. and room temperature (25° C.) andat 45° C., after 1 month and even after 2 months, i.e., no phaseseparation or exudation, although the feel of this composition was notparticularly pleasant. With composition 4, good stability was obtainedat 4° C., 25° C. and 45° C., after 1 month and 2 months. Thiscomposition felt pleasant, non-greasy, light and fondant on the fingersand was easy to spread.

[0287] The composition of Example 4 was also compared with acommercially available transfer-resistant foundation, Teint Idole instick form, containing conventional waxes, and no structuring polymer inthe sense of the invention. These compositions were applied perhalf-face to 5 testers and per half-neck to 10 individuals, afterapplying a day cream to the face and the neck (Primordiale fromLancôme), followed by drying for 10 min. and wearing a collar made offabric for 30 min. The extent of the deposit was assessed visually by anaesthetician. The transfer-resistance properties were graded from 0 to 7with 0 corresponding to no deposit of foundation on the collar, and 7corresponding to a sizeable deposit. Composition 4 according to theinvention received an average score of 2.6, compared with 3 for thecommercially available product, considered by the consumers as a verygood transfer-resistant product in stick form. In particular, 5 testersconsidered that composition 4 had transfer-resistance properties thatwere superior to those of the commercially available product, and 3other testers considered that composition 4 and the commerciallyavailable product had identical transfer-resistance properties.

[0288] Finally, these 2 compositions were considered as applying well,feeling soft, being comfortable and giving a natural and light make-upeffect. The skin was made uniform and smooth. The make-up effect washomogeneous.
